Creating Cinnamon Roll Bread Pudding is straightforward when you follow these easy steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Grease a large baking dish with butter or non-stick spray.
2. Prepare the Rolls: Cut your day-old cinnamon rolls into bite-sized cubes and place them in the greased baking dish.
3. Make the Custard: In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined.
4. Combine: Pour the custard mixture evenly over the cinnamon roll cubes. Gently press down on the cubes to ensure they soak up the custard.
5. Add Mix-ins: If desired, sprinkle raisins or chopped nuts over the top for added texture and flavor.
6. Top with Extra Rolls: For a more decadent finish, place additional cinnamon rolls on top of the mixture.
7. Bake: Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the pudding is set and golden brown on top.
8. Cool: Once baked, remove the pudding from the oven and allow it to cool for 10-15 minutes.
9. Dust: Before serving, dust with powdered sugar for an elegant touch.
